The calculation of diluted earnings per share for the three and six months ended March 31, 2013 and 2012 excludes shares of common stock related to approximately 289,000 and 562,000 outstanding stock options, respectively, because such options were anti-dilutive. These options could potentially dilute basic earnings per share in the future.
